4.5.1 Interrupts

• #define INTERRUPT_GlobalInterruptEnable() (INTCONbits.GIE = 1)

  This macro will enable global interrupts.

• #define INTERRUPT_GlobalInterruptDisable() (INTCONbits.GIE = 0)

  This macro will disable global interrupts.

• #define INTERRUPT_GlobalInterruptStatus() (INTCONbits.GIE)

  This macro will return the global interrupt enable bit status.

• #define INTERRUPT_PeripheralInterruptEnable() (INTCONbits.PEIE = 1)

  This macro will enable peripheral interrupts.

• #define INTERRUPT_PeripheralInterruptDisable() (INTCONbits.PEIE = 0)

  This macro will disable peripheral interrupts.

• #define EXT_INT_InterruptFlagClear() (PIR0bits.INTF = 0)

  This routine clears the interrupt flag for the external interrupt, INT.

• #define EXT_INT_InterruptDisable() (PIE0bits.INTE = 0)

  This routine clears the interrupt enable for the external interrupt, INT, and thereafter external interrupts on this pin will not be serviced by the interrupt handler.

• #define EXT_INT_InterruptEnable() (PIE0bits.INTE = 1)

  This routine sets the interrupt enable for the external interrupt, INT, and thereafter external interrupts on this pin will be serviced by the interrupt handler.

• #define EXT_INT_risingEdgeSet() (INTCONbits.INTEDG = 1)

  This routine set the edge detect of the extern interrupt to positive edge, and thereafter interrupt flag will be set when the external interrupt pins level transitions from a low to high level.

• #define EXT_INT_fallingEdgeSet() (INTCONbits.INTEDG = 0)

  This routine set the edge detect of the extern interrupt to negative edge, and thereafter interrupt flag will be set when the external interrupt pins level transitions from a high to low level.

• void __interrupt ()

  This routine services the ISRs of enabled interrupts and is called everytime an interrupt is triggered.

• void INTERRUPT_Initialize (void)

  Initializes Peripheral Interrupt priorities; Enables/disables priority vectors; and, Initializes External Interrupt.

• void INT_ISR (void)

  This ISR will execute whenever the signal on the INT pin will transition to the preconfigured state.

• void INT_CallBack (void)

  Allows for a specific callback function to be called in the INT ISR and allows for a non-specific interrupt handler to be called at runtime.

• void INT_SetInterruptHandler (void(*InterruptHandler)(void))

  Allows selecting an interrupt handler for EXT_INT - INT at application runtime.

• void INT_DefaultInterruptHandler (void)

  This is the default interrupt handler which is called every time the INT ISR is executed and allows any function to be registered at runtime.

• void(* INT_InterruptHandler )(void)

  This is the dynamic interrupt handler which is called every time the INT ISR is executed and allows any function to be registered at runtime.

#define EXT_INT_fallingEdgeSet( ) (INTCONbits.INTEDG = 0)

This routine set the edge detect of the extern interrupt to negative edge, and thereafter interrupt flag will be set when the external interrupt pins level transitions from a high to low level.

#define EXT_INT_InterruptDisable( ) (PIE0bits.INTE = 0)

This routine clears the interrupt enable for the external interrupt, INT, and thereafter external interrupts on this pin will not be serviced by the interrupt handler.

#define EXT_INT_InterruptEnable( ) (PIE0bits.INTE = 1)

This routine sets the interrupt enable for the external interrupt, INT, and thereafter external interrupts on this pin will be serviced by the interrupt handler.

#define EXT_INT_InterruptFlagClear( ) (PIR0bits.INTF = 0)

This routine clears the interrupt flag for the external interrupt, INT.

#define EXT_INT_risingEdgeSet( ) (INTCONbits.INTEDG = 1)

#define INTERRUPT_GlobalInterruptDisable( ) (INTCONbits.GIE = 0)

This macro will disable global interrupts.

#define INTERRUPT_GlobalInterruptEnable( ) (INTCONbits.GIE = 1)

This macro will enable global interrupts.

#define INTERRUPT_GlobalInterruptStatus( ) (INTCONbits.GIE)

This macro will return the global interrupt enable bit status.

#define INTERRUPT_PeripheralInterruptDisable( ) (INTCONbits.PEIE = 0)

This macro will disable peripheral interrupts.

#define INTERRUPT_PeripheralInterruptEnable( ) (INTCONbits.PEIE = 1)

This macro will enable peripheral interrupts.

void __interrupt ( )

This routine services the ISRs of enabled interrupts and is called everytime an interrupt is triggered.

void INT_CallBack (void )

Allows for a specific callback function to be called in the INT ISR and allows for a non-specific interrupt handler to be called at runtime.

void INT_DefaultInterruptHandler (void )

This is the default interrupt handler which is called every time the INT ISR is executed and allows any function to be registered at runtime.

void INT_ISR (void )

This ISR will execute whenever the signal on the INT pin will transition to the preconfigured state.

Section: External Interrupt Handlers

void INT_SetInterruptHandler (void(*)(void) InterruptHandler)

Allows selecting an interrupt handler for EXT_INT - INT at application runtime.

void INTERRUPT_Initialize (void )

Initializes Peripheral Interrupt priorities; Enables/disables priority vectors; and, Initializes External Interrupt.
